postgres barfage revisted
First of all, I''d like to do what I''ve seen several others here do:
thank Ezra and any other contributors for producing a really great
plugin. Even though I''m having some minor problems, this is all so
approachable and easy to work with and dig into... I hate to think of
the hoops you''d need to jump through (both as creator of such a system
and as a user) to

best approach to managing workers and getting status
Hi,
I am using backgroundrb to process audio files from a rails
controller. Currently a new worker gets created every time the method
is called on the worker, using this code:
@job_key = MiddleMan.new_worker(:worker
=> :audio_file_worker, :job_key => Time.now.to_i)
MiddleMan.worker(:audio_file_worker,
@job_key).make_new_audio_file(params[:release_id])
I need to create the new

periodic scheduling
I''ve been using backgroundrb since back in March 2007 or so. It''s
been working mostly OK for me, but since the old version doesn''t seem
to work out of the box with rails 2.0 for me, I decided to test out
the latest version.
So, I''m looking at the scheduling, and trying to figure out the best
option for what I want to do. What I have is a set of workers that

backgroundrb scheduler
I''ve been having a terrible time with the backgroundrb scheduler. The
issues I''m having is that the scheduled actions aren''t ran at all and if
they do, the process stays around forever. I''m using the backgroundrb as a
nightly cron to run some accounting operations.
questions:
1. How can I have the process destroyed after the worker completes?
2. Any idea on

Recommendations for eternally-running backgroundrb workers?
I''ve got some workers that I want to have running all the time. Right
now I''m just launching them manually, by requesting a special page in
my rails app that includes lines like:
MiddleMan.new_worker(:class=> :receiver, :job_key=>:r,
:args=>{:sleep_time=>10})
This strikes me as a really weak way to fire up my workers. I
basically want to automate things so

Deploying to production with backgroundrb (capistrano)
I have noticed that occasionally (about 50% of the time) when i
deploy (using capistrano) my app to a production server, i have to
ssh into the box and manually
stop and start backgroundrb to get it to load my workers.
this is my basic setup
i have 2 workers:
lib/workers/mp3_worker.rb => takes a hash of params to downsample an

worker starting twice
Hi gang,
Thanks to other help I''ve gotten on this list, I''ve got backgroundrb
up and running using postgres alongside my rails app. I''ve designed
the system to have several eternally-running workers that periodically
poll the database to see if there''s any work for them to do, and set
things up in the config file to make them restart quickly if any of
them

Can BackgrounDrb help me?
I have a big report to produce from a Rails app that takes several minutes
to put together. I hoped backgroundrb would be able to pull together all
the ActiveRecord stuff in the background then throw it back to Rails for
rendering.
It seems, however, that I can''t pass an array of ActiveRecord objects from
the worker back to Rails. Do I have that right?
Another possibility was to do

Thread Pool Size?
Hi All,
It might be lack of sleep, but I am struggling to accurately limit our pool
size. It seems like I can specify it on the server with the -s command
line option and also on the client via the YAML pool_size. Is that right?
Which one wins?
Our problem is that we are getting about 40 threads on each backgroundrb box
and it''s flooring our db and each bgrb box.
We want around 8.

example code for file upload
I have an archiving application that handles large file uploads. I
already use backgroundrb to run a behind the scenes bulk import of
records. All good. Thank you Ezra.
Now I would like to add long running file uploads to the things that
backgroundrb does for me. That''s right that ole chestnut. I''ve seen
a lot of mention of this practice around the web, but have yet

Scheduled workers only run once unless you call self.delete inside the worker
I had a worker scheduled to run every minute with
backgroundrb_schedules.yml:
ebay_runner:
:class: :ebay_auction_worker
:job_key: :ebay_auction_runner
:trigger_type: :cron_trigger
:trigger_args: 0 * * * * * *
This worker posts an auction to eBay from a queue of auctions every minute.
I was having a problem where the worker would run ok the first time, but
never any subsequent minutes

Noob needs help installing backgroundrb on Windows XP
Hey Guys,
In the readme for Backgroundrb it says that windows support has been
depcreated for this version, but then it goes on to mention how to use
it in Windows. So I''m not sure if it should be running on windows or
not, so I''ll ask anyway. Also, I''m new to ruby and I''m also new to
server administration, so I apologize if my questions are pretty

logging problem in production
Greetings all;
I''ve just moved my app into production and BackgrounDRb is writing to development.log. The backgroundrb.yml file specifies production, as does environment.rb.
A little background (no pun intended ;-0 ) I''m using the ''old'' version of backgroundrb for session management. In the app, whenever a visitor changes pages I record the time in a db

I''ve a class that try to spawn two workers, every 5 seconds.

I''m using Backgroundrb as a general purpose long-running-task back-end

However I''ve recently run into some some intermittent connection issues
that have me baffled. I''m running on apache2/fcgid and the problem

getting started
Hey all,
Been reading through all the old posts (and the docs) to familiarize
myself but I still feel a bit lost.
I''m on trunk and am having a bit of a hard time knowing where to start
with the particular I''m trying to solve.
So far, I''ve downloaded backgroundrb, done the basic rails setup,
created my worker and started it using `script/backgroundrb start`.
